The picture inside the app is the first picture within the article usually. However for the article metoprolol this does not occur? Wondering why?

If I'm correct, the logic for this is in Extension:PageImages, which job it is to filter and select an appropriate image from the page and provide that. In this case, i suspect that the image is every so slightly too small (probably in height) to be recognized as a good candidate. Alternatively it can be that it has trouble finding it inside this specific type of infobox.
